Repeatedly crashing while scanning ext HD (macOS 11.3.1)

[adamsaltman]

Scanned a 4TB ext HD (ext4 formatted, using extFS kernel ext) just fine, but when scanning a 2TB ext HD (also ext4 via extFS) now crashes multiple times. Have checked the disk and no errors.

To Reproduce
Start dupeGuru
Select disk (/Volumes/TempHD)
Select application mode Pictures, scan type Content
Click Scan
Crash after about 15 minutes of working

Desktop (please complete the following information):

• OS: macOS 11.3.1 on a 2020 mac mini M1 8GB/512GB

This is fixed in recent versions.

@adamsaltman I would encourage you to try out one of the two builds available over at #761 (comment) as many of the 4.0.3 issues have been fixed in the last few releases.

@adamsaltman The latest release (https://github.com/arsenetar/dupeguru/releases/latest) has built packages, I believe it should fix this issue as noted.
